CAP FOR MILK-BOTTLES AND THE LIKE.

Application filed March 29, 1918.

Y 'o m! whom it may concern Be it known that we, VILLIAM A. GIN- NERYand EDWARD U. SLoAN, citizens of the United States, residing at Bremen,in the county of F airfield, State of Ohio, have invented a new anduseful Cap for Milk-Bottles and the like; and we do hereby declare thefollowing to be a full, clear, and exact description of the inventlon,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to an improved cap for milk bottles and the like,and one of the objects of the invention is to provide means whereby thecap is carried permanently by the neck of the milk bottle. said means toe actuated for removing the cap, when it is desired to use the contentsof the bottle.

A further object of the invention is to provide an improved capconstructed of any suitable material, preferably sheet metal, forinstance sheet tin, copper, aluminium and the like, preferablyaluminium.

A further object of the invention is to provide a sheet metal capprovided with a marginal upstanding annular flange, said flange beingyieldable, and adapted to be contracted in diameter when forcing the capin contact with the supporting shoulder of the open end of the bottle.for holding the cap frictionally in place.

A further object of the invention is to provide a flan e on the capprovided with scallops or V-s aped cuts, so that the parts between thescallops or cuts may yield outwardly to hold the cap frictionally inplace.

If desired the scallops or cuts may be dis pensed with, and in eithercase the cap may be formed by placing the sheet metal over a former andpressing the same to form the flange.

In practical fields the details of construction may necessitatealterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts ashereinafter set forth shown in the drawings and claimed.

In the drawings Figure 1 is a View in perspective of a. month end of abottle, showing the cap applied, illustrating the means for permanentlyattaching the cap to the bottle.

Fig. 2 is a perspective view of the mouth end of the bottle, showing thecap removed, but attached to the bottle.

Fig. 3 is a sectional view on line 33 of Specification of LettersPatent.

Serial No. 225,410.

Fig. 1. showing the cap engaging the shoulder of the month end of thebottle.

Fig. 1 is a detail perspective view of the cap showing the scallops orcuts of the flange dispensed with, however, in this case the cap is alsoto be permanently attached to the month end of the bottle.

Referring more especially to the drawings, 1 designates the neck portionof a milk bottle, the mouth end thereof, and 3 the shoulder on theexterior of the neck, and surrounding the neck in engagement with theshoulder 23 is wire ring 4. This ri is made from a single length of wirewit its ends twisted together as shown at 5. Attached to the ring eitherto the twisted ends as at 6 in Fig. 1 or as at 7 in Fig. 2 is a suitablechain or the like 8, the other end of which is attached to an eye 9carried by the cap 10. This eye is secured to the cap in any suitablemanner, preferably as by a riveted holder 11. The mouth end of thebottle on its interior is provided with the usual su porting shoulder12. The wall 13 of t 6 month end of the bottle, that is upwardly beyondthe shoulder 12 is tapered slightly upwardly. in other words conical.The taper of this wall in reality, as is obviously known is hardlyperceptible by the naked eye, but nevertheless the taper exists. The cap10 is designed to be constructed from any suitable sheet metalpreferably aluminium, and is designed to engage the shoulder 12. Informing the cap, by compressin the sheet metal over a former (not shownas is usually accomplished when forming a flange, the cap is providedwith a mar inal annular flange 14, which is desi e to spring outwardlyagainst the tapere wall 13, after the cap has been sprung by or passedthe smaller diameter of the wall 13, thereby holding the capfrictionally in place. In Figs. 1, 2 and 3 the flange 14 is providedwith a plurality of scallops or cuts 15 (which may be any suitableshape), which form the intermediate lugs 16, which may more readilyspring outwardly. In Fig. 4 the scallops or cuts are eliminated. It isto be noted that by means of the chain 8 the cap is permanently or atall times carried by the bottle, and when it is desired to remove thecap, a pulling action may be imparted on the chain, which will lift thecap from its seat from the mouth end of the bottle. By providing a largenumber of closely related elements adapted to individually spring intoengagement with the substantially vertical inner wall of the bottle neckthe structure is caused to form a tight joint at all points about thecircumference of the bottle neck irrespective of whether the bottle neckdescribes a true circle or not, it being well known that a largeproportion of the molded bottles commonly used are not truly circular.

The invention having been set forth What is claimed as new and useful isA metallic cap for milk bottles and the like comprising a disk member ofresilient material having an upstanding marginal flange, said marginalflange being closely notched with V-shaped notches around its upper edgethereby forming a pluralityof closely related spring lugs for engagingthe vertical inner wall of a bottle neck and preventing displacement ofthe disk by frictionally binding against the inner face of the bottleneck at all points in the circumference thereof and below the top ofsaid vertical wall. 7

In testimony whereof We have signed our names to this specificationinthe presence of two subscribing witnesses.
